如果我停滞不前，就会生锈。

If I rest, I rust.

我认为经济在缓慢增长的水平上停滞不前。

I think the economy is stuck on a plateau of slow growth.

《柯林斯英汉双解大词典》

如果你所效力的公司正为成功而奋斗，或者感觉停滞不前、脱离(跟不上)时代，那么你是很难为工作而兴奋的，我还不是在谈论那些明显的问题——赤字和裁员。

It's hard to be thrilled with your job if the company you work for is struggling to succeed, or feels stuck and irrelevant. I'm not talking about obvious problems — red ink and layoffs.
